Specifying high-temperature hot-water boilers and

High-temperature hot-water (HTHW) plants are typically designed to operate at temperatures ranging from 350°F to 420°F. The system pressure must be at least 25 psig above the saturation pressure of the high-temperature water's maximum temperature to prevent pump cavitation and flashing of superheated water

Deaerator feed water pump location. Location: Boiler feed water pump takes suction from DA Storage tank. some of the saturated water can be flash into steam due to suction pressure, which may cause cavitation Problem in BFW Pump. To prevent this deaerator should be placed at sufficient height So it provides NPSHA to pump.

Having said all of that, sometimes a crackling or banging sound on the suction side of a pump is cavitation, which is related to the velocity at the inlet of the pump and occurs because of the reduction in static pressure associated with the increase in velocity that occurs as the water accelerates into the eye of the impeller.

An ejector cooling system (ECS) is a mechanical system utilizing the Rankine cycle and the gas dynamic effect of an ejector (a thermal compression process). The basic ejector refrigeration cycle is illustrated in Figure 12.The system consists of two loops, the power loop and the refrigeration loop. In the power loop, low-grade heat, Q G, is used in a generator to evaporate high-pressure liquid

Boiler Feed Water System Diagram and Explanation -

2020-12-17 · In case the hot well overflows, the water goes to the feed water tank, which supplies feed water to the system whenever there is a dearth. A de-aerated type heater is used in the feed water line in order to remove any dissolved oxygen from the water. This is basically done to prevent corrosion of the boiler.
